About Photovoltaic Energy Storage8 amperes for 3 hours (8 x 3) = 24 Ah @ the 3-hour rate 30 amperes for 1 hour (30 x 1) = 30 Ah @ the 1-hour rate Therefore, if you have an application that requires a draw of 17 amperes for 3 hours, you would need a 51 Ah battery (@ the 3 hour rate)…(17 x 3 = 51). However, this is 100% of the capacity of this 51 Ah battery.

Lead-acid batteries designed for starting automotive engines are not designed for deep discharge. They have a large number of thin plates designed for maximum surface area, and therefore maximum current output, which can easily be damaged by deep discharge. Repeated deep discharges will result in capacity loss and ultimately in premature failure, as the electrodes disintegrate …
About Photovoltaic Energy StorageThis results in a precondition, the hour rate. Capacity is generally defined as the capacity based on a certain hour-rate. For example, a 12V100Ah lead-acid battery, based on a 10 hour-rate, means that 10A current can be discharged for 10 hours. And it can''t be discharged for 1 hour at 100A.
